HEATING APPARATUs.-

I Application filed April l0, 1895. Serial No. 545,142. (No model.)

ter, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Heating Apparatus, of which the following is a specification.

My invention relates to heating apparatus, and the object of my invention is to provide paratus, consisting of a steam or hot-water radiator of ordinary construction, combined directly with my apparatus forheating the water or producing the steam which circu i5 lates through the radiator; and myinvention consists in certain novel features of construction and combination of parts of my heating apparatus, as will be hereinafter fully described, and the nature thereof indicatedlby zo the claims.

I have shown in the drawings my heating apparatus as a hot-water heater.

Referring to the drawings, Figure 1 is a front view of my heating apparatus. Fig. 2 is an end view looking in the direction of arrow a, Fig, 1. Fig. 3 is, on an enlarged scale, a vertical cross-section throughthe lower part of the heater on line 3 3, Fig. 1,looking in the direction of arrow a, same figure. Fig. tis, 3o on an enlarged scale, a central vertical longitudinal section through the lower part of the heater on line 4 4, Fig. 2, looking in the direction of arrow b, same ligure. Fig. 5 is a plan view of the boiler removed; and Fig. 6 is 3 5 a vertical cross-section through the watertank on top of the radiator taken on line 6 6, Fig. 1. l In the accompanying drawings, 1 is a radiator of ordinary construction, consisting of a per and lower ends, as shown in Fig. 2, and

having a horizontal connecting-pipe 3 at the 'top of the radiator and another horizontal connecting-pipe 4 at the bottom of the radiator, connecting the Vertical pipes 2, so that there may be a continuous circulation of hot water or steam through the radiator in the ordinary way.

Combined with the radiator 1, and in this 5o instance located directly under it, is my apparatus for heating the water which circulates through the radiator, or for producing the steam which circulates through the radiator.

My apparatus consists of an inclosed chamber or box 5, having, in this instance, thetwo vertical ends 6, provided with legs or supports 7 for holding the box 5 above the floor, to leave a space under said box for the circulation of air, and the back 8, front 9, and top 10, combined with the ends 6 to form an in closed chamber. t

The bottom 11 or lower part of the box 5 is in this instance made double, and supported on extensions 7, extending inwardly from the lower part of the ends 6. The bottom 11 consists in this instance of two plates 11 and 11", joined at their ends and sides to form an' inclosed air-chamber, as shown in Figs. 3 and 4. The plates lland 11a re provided with a series of holes 12 therein, through which air enters from the room in which the heating apparatus is used into the burnerchamber. lf preferred, air from out doors or from any other place may enter the bottom 11 through a pipe 13. leading into the back of the bottom 11, as shown in Figs. 2 and 4. Extending directly over and resting upon the bottom 4 are, in this instance,two metal pipes 13 and 14, closed at their inner ends and provided with a series of holes l5 upon their upper surface. The pipes 13 and 14act as burners for vthe gas, which enters said pipes through their outer ends, which extend through one end of the lbox 5. Each pipe is provided with a separate stop-cock or shutoff valve 16, as shown in Fig. 2, and connected with both pipes and leading to the stop-cocks is, in this instance, one pipe 17, one end of which is closed and the other end connected with a rigid or flexible pipe 18, leading from a gas supply-pipe, not shown.

The pipes 13 and 14 extend loosely through the holes in the end of the box 5, so that they may be readily drawn out or pushed in for any purpose, if desired.

The front of the box 5 is provided in this instance with two sliding doors 19, of transparent material, as isinglass, che., which can be opened and closed to allow of access to the pipes 13 and 14 to light the gas coming through the holes Y15 therein.

IOC

Located within the box 5, and arranged directly over the pipes or burners 13 and 14, and in this instance supported on lugs 20, extending inwardly from the ends 6, is the boiler 21, which holds the water that is heated by the burners 13 and 14.

A pipe 22 leads out of one end of the boiler 2l, through which the heated water passes into the radiator, and a pipe 23.leads out of the other end of the boiler, through which the water enters the boiler from the radiator. The pipe 22 is coupled in this instance to a vertical pipe 24, which extends upon the outside of the-radiator and leads into the upper part thereof, and the pipe 23 is coupled to a pipe 25, leading out from the lower part of the radiator, as shown in Fig. 1.

In order to prevent any odor of escaping gas from the box 5, I preferably provide a pipe 26, leading out from the rear side of said box and extending into a chimney or standpipe.

In order to fill the radiator l and boiler 2l with water I preferably arrange on top of the radiator 1 a tank or receptacle 27, in thisinstance extending over the whole top of the radiator, as shown, and provided with a removable cover 28. The tank 27 is connected with the radiator l, in this instance, by a pipe 29, extending through the bottom of the tank and into the top of the central vertical pipe of the radiator, as shown in Fig. 6.

A cock or valve 30 may be located at the lower part of the radiator to draw off the water if desired. i

From the above description, in connection with the drawings, the operation of my heating apparatus will be readily understood by those skilled in the art.

The cover 28 is removed and the water poured intothe tank 27 until the pipes of the radiator and the boiler 2l are filled with wa-`L ter. The gas-cocks are then turned to let the The size of the flame may be regulated as desired by the cocks, and one or both of the burners 13 or 14 may be used. The water in the boiler 2l is heated by the iiame and circulates through the radiator, which throws oiir' the heat. The water isV used over and over, and it is only necessary to add a small quantity at long intervals.

The advantages of my heating apparatus will be readily appreciated by those skilled in the art. It is ot' very simple construction and operation, and can be nsedanywhere in connection with any hot-water or steam radiator where there is a gas-supply pipe.

It will be understood that the details of construction of my heating apparatus may be Varied it` desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a heating apparatus, the combination, with a casing, of burners located therein, a boiler above and a chamber below the burners, the chamber having its top and bottom perforated, and being provided with an inlet opening, whereby air may be conveyed thereto from the exterior, and a radiator upon the casing communicating with the boiler, substantially as set forth.

2. In a heating apparatus, the combination, with a casing, the interiorof which is provided with inwardly projecting lugs, one wall is pro-V vided with doors and the opposite wall is provided with two opeuings, a boiler withimthe casing, upon a portion of the lugs, a chamber upon the other lugs, said chamber having its top and bottom perforated and communicating with one of the openings in the'wall, and burners between the boiler and the chamber, the other opening in the wall ot' the casing forming an outlet for the products ot' combustion, substantially as set forth.
